“From April to June, our crews performed twice monthly closures to clean and complete preventative maintenance along I-93 through Boston. In August, this effort will focus on the I-90 Ted Williams Tunnels,” said MassDOT Highway Administrator Frank DePaola. “Our maintenance teams report the I-93 tunnels are the cleanest they have been since first opening.”

Interstate 90 Eastbound traffic destined for East Boston and Logan Airport will be directed north onto Atlantic Avenue/Cross Street and make the turn to the Callahan Tunnel at Valenti Way/Beverley Street. A second detour will be active for truckers. Trucks will be directed to utilize the I-93 NB on ramp from Atlantic Avenue at the Seaport Blvd. intersection to Exit 27 Route 1 NB (Tobin) in order to access Route 16 Eastbound to Route 1A Southbound.

Maintenance crews, contractors, along with State and Boston Police will begin set-up for the lane closures on Tuesday evening at 11pm. The full closure will begin at midnight on Wednesday and last until 5am Wednesday morning.

Work to be performed August 7 to 8 includes: cleaning drains and washing walkways, ceilings and walls.

Plan Ahead- Complete Lane Closure Dates for the Month of August:

I-90 Westbound Tuesday, August 21 from 11pm to Wednesday, August 22 at 5am.

Complete lane closures are planned for the month of September. Depending upon the progress made along I-90 this month, MassDOT will determine whether to continue with the I-90 work in September or return to maintenance of I-93.
